Comparing Day 3 vs Day 5 Embryo Transfer for IVF With Few Embryos
This trial compares transferring embryos at the cleavage stage (day 3) versus the blastocyst stage (day 5) for women who have few embryos during an IVF cycle. It may help determine which stage gives the best chance of pregnancy for people with limited embryos.
Boston, MassachusettsAges 18–44 - NCT06524648Recruiting
Non-invasive embryo development check for frozen transfers
This study tests a new non-invasive way to check how embryos are developing before they are frozen and later transferred. It looks at fluid around the embryo to see if it can give extra information about embryo health.
DoblAges 20–42 - NCT06710769Recruiting
Ovarian tissue freezing before cancer treatment
This study helps people who are about to start cancer treatment (or have certain health conditions) preserve their ability to have children later. It removes and freezes a small piece of ovarian tissue before treatments that could damage the ovaries.
Phoenix, ArizonaAges 1–25 - NCT06701071RecruitingPhase 4
Comparing short vs long Clomid for IVF stimulation
This study tests whether a shorter or longer course of Clomid (a fertility medicine) works better for women who are expected to have a low response to ovarian stimulation. It may help those with a lower egg reserve still produce enough eggs for IVF.
Pasadena, CaliforniaAges 18–44 - NCT06304792Recruiting
Immediate vs. later frozen embryo transfer in women with regular or irregular cycles
This trial compares transferring a frozen embryo right away versus waiting for a later cycle. It is designed for women with regular or irregular menstrual cycles who have at least one good-quality frozen embryo.
CopenhagenAges 18–40 - NCT06686537RecruitingPhase 2
Study on metabolism and hormones in women
This study looks at how metabolism and hormones are connected in women. It tests a treatment to see if it can improve metabolic health related to the menstrual cycle.
Aurora, ColoradoAges 18–38 - NCT06644794RecruitingPhase 3
Progesterone timing for frozen embryo transfer
This trial compares two ways of timing progesterone support for frozen embryo transfer in women with regular cycles. It aims to find which approach gives the best chance of pregnancy.
Jinan, ShandongAges 21–44 - NCT04959864Recruiting
Food supplement study for sperm DNA damage in men
This trial tests whether a daily food supplement (with myo-inositol, N-acetyl-cysteine, zinc, and vitamins) can reduce sperm DNA damage. It enrolls men with higher-than-normal sperm DNA fragmentation, and it checks semen health during the study.
ParisAges 20–45 - NCT06629766Recruiting
Study on how father's age affects embryo growth
This study looks at how the father's age might affect the growth of embryos in the lab. It is for couples doing their first IVF cycle, planning to test embryos for genetic health before freezing them, and then transferring one healthy embryo.
Basking Ridge, New JerseyAges 18–41 - NCT06601452Enrolling by invitationEarly Phase 1
Chinese medicine for anovulatory infertility in IVF
This trial tests a treatment for women with infertility caused by ovulation problems, like PCOS or low ovarian reserve, or when IVF is needed due to a male factor. It aims to see if a Chinese medicine approach can help improve IVF success.
Nanjing, JiangsuAges 20–41 - NCT04477863Recruiting
Follow-up study for people who had genetic testing in embryos
This trial follows up with people who chose to participate in research when getting preimplantation genetic testing (testing genes in embryos). It may help researchers understand outcomes and improve future genetic testing and counseling.
North Brunswick, New JerseyAges Any age - NCT04167748Recruiting
Genetic testing for embryos in IVF for women 35–40
This study looks at using embryo genetic testing before pregnancy in IVF for women aged 35 to 40. It may help by identifying which embryos are more likely to lead to a healthy pregnancy, though you would still be screened to confirm you fit the criteria.
Margate, FloridaAges 35–40 - NCT06141135Recruiting
Genetic testing in IVF with single embryo transfer
This trial is for women aged 35–40 doing IVF. It compares genetic testing of embryos before transfer to standard care, to see if it improves pregnancy success.
Waltham, MassachusettsAges 35–40 - NCT06583395Enrolling by invitation
Meditation retreat study with fitness tracker
This trial studies people attending a 7-day meditation retreat to see how meditation affects well-being. You will wear a fitness tracker and answer surveys.
Palm Desert, CaliforniaAges 21 years+ - NCT06581068Recruiting
Automated IVF lab study for better fertility outcomes
This study tests a new automated system for IVF lab procedures to see if it improves success rates. Patients with specific fertility needs may join if they meet health and age requirements.
Mexico City, Mexico CityAges 18–45 - NCT06561451Recruiting
Comparing two IVF methods for severe sperm shape issues
This trial compares two lab techniques (ICSI alone vs. ICSI with AOA) to see which leads to more live births for couples where the male partner has very abnormal sperm shape (99-100% abnormal). The study focuses on women aged 20-37 who are undergoing fertility treatment.
ShanghaiAges 20–37 - NCT06041204Recruiting
Thyroid hormone plus letrozole for PCOS and mild hypothyroidism
This trial tests whether adding a low-dose thyroid hormone (levothyroxine) to the standard fertility treatment letrozole improves pregnancy rates in women with both PCOS and mild hypothyroidism. It may help if you have trouble getting pregnant and have these two conditions.
CairoAges 20–40 - NCT06492785Recruiting
Hyaluronic acid in embryo transfer for better success
This trial tests whether adding hyaluronic acid to the fluid used during embryo transfer helps more embryos implant, leading to a successful pregnancy. It's for people having a single embryo transfer with their own eggs.
Xi'an, ShaanxiAges Any age - NCT06193135Recruiting
Comparing two ovarian stimulation medications for egg donors
This trial compares two different medications (Corifollitropin alpha and daily rFSH) to stimulate egg production in healthy egg donors. It aims to see if a single injection of Corifollitropin alpha works as well as the usual daily shots, making the process simpler and more comfortable.
Valencia, ValenciaAges 18–35 - NCT06414096RecruitingPhase 1
Pulsatile FSH study for women with obesity or low ovarian reserve
This study tests a new way to give a fertility hormone (FSH) in pulses through a small tube to see if it helps women with obesity or low egg reserve have better egg development with fewer health risks. It may improve fertility treatment outcomes for these women.
Aurora, ColoradoAges 19–37 - NCT06023602Recruiting
Generic vs. brand-name cetrorelix for IVF ovarian stimulation
This trial compares a generic version of cetrorelix acetate (a medication used to control ovulation) to the brand-name version during IVF. It aims to see if the generic works just as well for women undergoing ovarian stimulation.
Xi'an, None SelectedAges 20–42 - NCT06377917Recruiting
Testing timing of assisted hatching in IVF
This study compares two different timings for a lab procedure called assisted hatching (making a small opening in the embryo's outer shell) to see if one helps more embryos implant. You may be eligible if you're doing IVF with a frozen embryo transfer of a single screened embryo.
Marlton, New JerseyAges 18–42 - NCT06212102RecruitingPhase 2
Comparing two drugs for poor responders in double ovarian stimulation
This trial compares dydrogesterone with a GnRH antagonist to see which works better for women with a low number of eggs (poor responders) who are undergoing two rounds of egg retrieval in one cycle. It may help improve outcomes for those with specific fertility challenges.
Cairo, Cairo GovernorateAges 35–44 - NCT06165367Recruiting
Does hyaluronan in the medium improve embryo transfer success?
This trial tests if adding hyaluronan to the liquid used during embryo transfer helps increase the chance of a successful pregnancy. It is for women who have at least one genetically normal embryo (tested with PGT-A) that was frozen on day 5 and are using hormone replacement therapy to prepare the uterus.
